The number of cows in a farm was 60% of the number of the goats. After 80 goats were taken out of the farm, the number of goats became 60% of the number of cows in the farm.
(a)how many cows were there in the farm?
(b) what is the percentage of the goats were moved out of the farm?

Answers

Before:
The number of goats =60%
The number of cows = 100%

Using ratio
Cows : Goats
60 : 100 reduced to simplest term

C:G
3:5

After
The number of cows = 100%
The number of goats = 60%

Using ratio

C:G
100:60 reduced to simplest term
C:G

Use the distributive property of multiplication to find 7 x 22

Hint: 22 = 20 +2

Please show all work, Thank you:)

Answers

We multiply 7 by 20 to get 140. We also multiply 7 by 2 to get 14. Add 140 to 14 to get 154

Here's how you can write it out
7 x 22 = 7 x (22)
7 x 22 = 7 x (20+2)
7 x 22 = 7x 20 + 7 x 2 ... distributive property
7 x 22 = 140 + 14
7 x 22 = 154

Answer: 154

Final answer:

The distributive property of multiplication is used to simplify 7 x 22. By substituting 22 with 20 + 2 and distributing the multiplication, it becomes 7 x 20 plus 7 x 2, which equals 154.

Explanation:

The question is asking us to use the distributive property of multiplication to calculate 7 x 22. The distributive property allows us to multiply a single term and two or more terms inside a set of parenthesis. Here we are given the hint that 22 = 20 + 2.

Following the hint, we substitute 22 with (20 + 2) in the multiplication expression. So, 7 x 22 becomes 7 x (20 + 2). Now, by distributive property, we can take the multiplication inside the parenthesis.

7 x 20 = 140 7 x 2 = 14

By adding both these results, 140 + 14, we get the final answer 154.

First Question 3a–a+18–a
Second Question (a+3)–(a+2)
Third Question 43+a–2a

Answers

1. 3a - 1 + 18 - a

So you can reorder these, as long as they keep the sign in front of them.

3a - a - 1 + 18, you can reorder it to.

And then just add or subtract.

2a + 17

2. (a+3) - (a + 2)

First you want to open the parenthesis.

To do that, check the symbol before the parenthesis.

If it's a minus, reverse the operator inside the parenthesis. If it's a plus, do nothing.

So just,

a + 3 - a - 2

Then reorder again

a - a + 3 - 2

3. 43 + a - 2a

Just subtract, a - 2a, to get -a.

So,

Answers

Use the vertical line test.
Think of a vertical line moving from left to right across the graph.
If the line touches more than one point on the graph at a time, it is NOT a function.
If the vertical line touches at most one piont ion the graph, then it is a function.

Look at the circle, on the top right.
As the vertical line moves to the right, it will touch two points of the circle; therefore, the circle is not a function.

Only one graph passes the vertical line test, and it is the bottom right graph.

Only the fourth graph, in the lower right-hand corner, represents a function. Note that in this graph, there is exactly one y-value for every x-value.

If there is more than 1 y value for any given x-value, you've got a relationship, not a function.

What is the solution to the inequality x2 >49 (x squared is greater than or equal to 49) plz help

Answers

To find the answer take the square root of both sides. You get x > plus or minus 7. Make sure to add positive AND negative 7!

To solve the inequality x² ≥ 49, take the square root of both sides and consider both positive and negative roots. The solutions are x ≤ -7 or x ≥ 7.

To solve the inequality x² ≥ 49, we need to consider the values of x that satisfy this condition. Let's break it down step-by-step:

Step-by-Step Explanation

x² ≥ 49. To solve this, we can take the square root of both sides of the inequality. Remember, when taking the square root of both sides, we must consider both the positive and negative roots.

Solve for x: |x| ≥ √49.

Since √49 = 7, the inequality becomes: |x| ≥ 7.

This implies x can be greater than or equal to 7 or less than or equal to -7.

Therefore, the solution is: x ≤ -7 or x ≥ 7.

In interval notation, this solution is written as: x ∈ (-∞, -7] ∪ [7, ∞).

A cake has a mass of 2.5kg. It contains 275g of fruit. What percentage of fruit is there in the cake

Answers

The answer is: "11 %" .
__________________________________
There is 11% of fruit in the cake.
______________________________
Explanation:
____________________________________

275g is what percent of 2.5 kg?

First, convert "275 g" into "kg".

Note the exact conversion: 1000 g = 1 kg .

So 275 g = (275/1000) kg = 0.275 kg .

0.275 kg = (n/100) * 2.5 kg ;

→ (n/100) * 2.5 = 0.275 ;
____________________________
Divide each side by "(2.5)"
______________________
→ (n/100) = (0.275) / (2.5) ;

→ (n/100) = 0.11 ;

Multiply each side by "100" ;

n = 11 .
________________________________________
The answer is: 11 % .

The percentage of fruit is there in the cake will be 11%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Mass of cake = 2.5 kg

And, The amount of fruit = 275 g

Now,

Find the percentage of fruit is there in the cake as;

Since, Mass of cake = 2.5 kg

= 2,500 g

And, The amount of fruit = 275 g

So, The percentage of fruit = 275 / 2,500 x 100

= 0.11 x 100

= 11%

Thus, The percentage of fruit is there in the cake will be 11%.
